Travel-gear startup Away is expanding its brick-and-mortar presence, an increasingly common business strategy for e-commerce ventures.

Like Warby Parker, where some of the company’s founders previously worked, Away has a direct-to-consumer sales approach. After shipping 100,000 suitcases since February 2016, the company is gearing up to expand into other travel-related goods.

To fuel those capital-intensive efforts, Away said it has raised $20 million in a Series B funding from existing investors. Global Founders Capital, which led the company’s Series A less than a year ago, returned as the lead investor. Existing backers Comcast Ventures, Forerunner Ventures and Accel Partners also participated.

“We’re just at a stage really where we should go into hyper-scale,” said Global Founders Capital Partner Ludwig Ensthaler. “There are so many obvious and untapped opportunities here for this company.”

The company, formally called JRSK Inc., said it has done $20 million in sales to date and plans to be profitable by the end of the year.

Away experimented with a pop-up store first in New York and then in other cities in the U.S. and Europe around the holidays. Following the success of those stores, Chief Executive Steph Korey said the company will move into four to six retail locations this year.

Other data-driven retailers are opening their own locations. Warby Parker, where Ms. Korey and her co-founder previously worked, lists about 50 brick-and-mortar locations on its website. Mattress startup Casper has also opened show rooms, and even earlier-stage businesses are dipping their toes into physical retail locations.

One of Away’s retail locations will open in London. At the time of the company’s Series A round last year, Away said it felt it should expand internationally at an earlier stage than many other e-commerce companies because of its focus on travel.

Away has tried to build an entire brand around travel, said Ms. Korey in an interview just an hour after flying back from her honeymoon in Turks and Caicos. One of the startup’s perks is an all-staff trip. This year about 45 employees went to Nicaragua together.

“Every company has different employee benefits,” she said. “That one feels very core to us as something we wouldn’t want to give up.”

Away plans to focus more on creating content, and on Friday it will launch a podcast. A travel magazine is in the works as well.
